Mizusawa High School's karuta club claimed victory in the team competition for the first time at the Nationals in July. However, before they could even take time to relax, Chihaya and Taichi agreed to take part in the Fujisaki High School karuta club's training camp. Awaiting them was Coach Sakurazawa's brutal training regime of stretching, jogging, and playing seven matches each day!

The audience at the Yoshino Tournament is taken for a wild ride with so many unexpected twists: Arata, the focus of high expectations, has been defeated, and Taichi, who only just reached Class A, advances to the finals. And now it's time at last for the final round between Chihaya and Taichi, teammates who have been practicing together since they were in elementary school. The odds are in Chihaya's favor, but Taichi isn't playing his usual karuta since he declared that he would defeat her in an official match.

Chihaya chooses to go on her class trip in hopes to come closer to fulfilling her dream of being a teacher, but she spends the entire time lost in space, wondering how Taichi is doing at the Master tournament qualifiers. Harada and Inokuma are also participating in the East Japan qualifiers, but as Taichi tries to quietly psych himself up, someone unexpected shows up to get in his way. Meanwhile, at the West Japan qualifiers, Master Suo makes a surprising comment to Arata.

Arata wonders why he feels so relieved to learn that Taichi lost his match, even as dark memories of a similar feeling at the Yoshino Tournament come back to him, leaving him unable to concentrate fully on his match in the finals. His opponent, Murao, realizes that Arata isn't himself and sees an opportunity, but then...

The club hosts an unofficial tournament, the Taichi Cup, to celebrate Taichi's birthday! Chihaya planned the event in hopes of cheering up Taichi, and she managed to gather 36 participants. The tournament is held in the style of a Genpei match, with competitors facing off in teams of three. Taichi is reminded of when he, Chihaya, and Arata used to play together in elementary school. Certain things have changed since then, but certain feelings haven't...

Taichi has told Chihaya about the feelings he had kept secret for so long. Now he's left the karuta club, and Chihaya's regret over failing to notice how he felt leaves her unable to play. But some new members have joined Mizusawa's karuta club, and among them is Tamaru Midori, a Class A player. She is a promising new member, but also a troublemaker.
